Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. T
MAVERICK [17]

Explanation:

It is given that,

Maximum electric field, E=10^{11}\ V/m

Time taken, t=1\ ns=10^{-9}\ s

(a) Maximum magnetic field, B=\dfrac{E}{c}

B=\dfrac{10^{11}\ V/m}{3\times 10^8\ m/s}

B = 333.33 T

(b) Intensity of beam, I=\dfrac{E^2}{2\mu_o c}

I=\dfrac{(10^{11})^2}{2\times 4\pi \times 10^{-7}\times 3\times 10^8}

I=1.32\times 10^{19}\ W/m^2

(c) Energy delivered by the pulse, E=I\times A\times t

E=1.32\times 10^{19}\times 10^{-6}\times 10^{-9}

E = 13200 J

Hence, this is the required solution.

A hydraulic lift has two connected pistons with cross-sectional areas 15 cm2 and 670 cm2. It is filled with oil of density 510 k
BigorU [14]

Answer:

Explanation:

Given

Cross-sectional area of two areas is

A_1=15\ cm^2

A_2=670\ cm^2

It is filled with oil of density \rho _0=510\ kg/m^3

mass of car place on Large area M=1100\ kg

Suppose a mass of m kg is placed on smaller area

According to pascal law's intensity of pressure is same at every point on Liquid

P_1=P_2

\frac{F_1}{A_1}=\frac{F_2}{A_2}

\frac{mg}{15}=\frac{Mg}{670}

m=1100\times \frac{15}{670}

m=24.62\ kg
